This　letter　studies　the　problem　of　anti-jamming　power　control　in　wireless　communication　systems　where　users　do　not　know　the　game　model.　When　the　transmission　loss　and　other　parameters　are　unknown,　we　use　the　Q-learning　algorithm　to　build　a　wireless　communication　system　with　anti-jamming　power　control　game　model.　The　user　utility　function　and　SINR　under　channel　gain　are　simulated　and　compared,　which　proves　the　better　anti-jamming　performance　of　the　algorithm.　©　2022　IEEE.
